I can get all codes working except power on!

I have set TV to UART, disabled anynet+ and set hotel power mode to power on which is all i can find from others on the internet. Anyone else got any suggestions?

The spreadsheet really is a fantastic resource, just can't get this last one working..

My powershell that i am using


#[Byte[]] $request = 0x08,0x22,0x00,0x00,0x00,0x01,0xD5 #off
[Byte[]] $request = 0x08,0x22,0x00,0x00,0x00,0x02,0xD4 #on

#[Byte[]] $request = 0x08,0x22,0x0d,0x00,0x00,0x99,0x30 #power 2
#[Byte[]] $request = 0x08,0x22,0x01,0x00,0x00,0x08,0xCD #vol 50
#[Byte[]] $request = 0xAA,0x11,0xFE,0x01,0x01,0x11,0x13
$port= new-Object System.IO.Ports.SerialPort COM3,9600,None,8,one
$port.Open()
$ret = $port.Write($request, 0, $request.Count)
$port.Close()
